WILLIAM G. MITCHELL, OF BROOKLYN, NEW YORK.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 224,209, dated February 3, 1880.

Application filed December 27, 1879.

To all whom it may concern Be it know that I, WILLIAM G. MITCHELL, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Gar-Axle Lubricators, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings, in which. I

Figure 1 represents a longitudinal vertical section. Fig.2 is a transverse vertical section.

Similar letters indicate corresponding parts.

This invention relates to that class of caraxle lubricators in which are employed a coiled spring supporting a roller and two pads in contact with the axle; and my invention consists in the combination of a spiral spring adapted to rest on the bottom of the axle-box, a porous flexible jacketinclosing the bottom and sides of the spring, a wiping-roller journaled within the spring, and a pad secured on the bottom of the flexible jacket for absorbing the oil from the bottom ofthe axle and bringing it within reach of wipers on the wiper-roll, as will be fully hereinafter described.

Inthe' drawings, the letter A designates a spiral-spring. B is a flexible jacket, by preference made of porous material. 0 is a wiperroller. -D are pads. E are wicks depending from or connected to the pads; and F is a sheet-metal frame, which supports the pads, and is provided with ears a a, forming the bearings for the axle or gudgeons ot' the wiperroller.

The spring A is made of suitable size to be introduced in a car-axle box, and may be round or square, while the jacket B is made of a textile fabric, preferably with open meshes, and stretched around and under the bottom of the spring, the same being fastened to the spring by stitching or other suitable means.

To the top of the spring Ais secured the sheet-metal frame F, which is provided with ears to a, projecting downward, and forming the bearings for the wiper-roller 0, said frame being open to admit the roller. The wipers b of the roller 0 are made of horsehair or other suitable material, of sufficient length to'extend to, or nearly to, the bottom of the axle-box when the lubricator is in position.

The pads D are composed of pieces of carpet, felt, or other like absorbent material, and

they are supported by the sheet-metal frame F on opposite sides of the roller C, said frame being flexible, so that the padscan be adjusted to conform to the diameters of different axles.

The wicksE are made of any suitable material, and they are sewed or otherwise fastened to the pads'D at their upper ends, so as to depend therefrom, their lower ends being preferably attached to the'spring A, as shown in Fig. 2.

On the bottom of the jacket B is secured a convex pad, G, made of any suit-able absorbent material which is adapted to raise the oil from the bottom, and particularly fromthe corners of the axle-box, and bring the same in reach of the wipersb.

In the practical operation of my'lubricator the oil contained in the axle-box flows through the jacket B, being thereby strained or filtered before it is applied to theaxle by the wiperroller 0, which revolves by contact with the axle, being pressed upward against said axle by the spring A. At the same time the pads D are supplied with oil by the wicks E, and if the oil in the axle-box gets low the convex pad Gr raises the same and brings it in reach of the wipers. I

I am aware that the combination of a spring, a flexible jacket, a wiper-roller, and an ab sorbent pad is not new, and I hereby disclaim the same.

What I claim as new, and desire to secure by Letters Patent, is

The combination, in a car-axle lubricator, of

aspiral spring adapted to rest on the bottom of the car-axle box, a porous flexible jacket inclosing said spring on'its sides and bottom, a wiper-roller journaled within the spring, and a convex pad secured on the bottom of the flexible porous jacket for absorbing the oil from the bottom of the axle-box and bringing the same in reach of the wipers, substantially as shown and described.

In testimony that I cla m the foregoing I have hereunto set my hand and seal this 22d day of December, 1879. 7

WILLIAM G. MITCHELL.
